- Introduction of MCP Apps Extension (SEP-1865) to standardize interactive user interfaces in the Model Context Protocol.
- Addresses community demand for UI support, building on MCP-UI and OpenAI Apps SDK.
- Standardizes UI resource declaration, tool linking, and bidirectional communication.
- Authored by MCP Core Maintainers at OpenAI and Anthropic, with MCP-UI creators.

- Risk of ecosystem fragmentation due to varied implementations.
- MCP-UI project led by Ido Salomon and Liad Yosef, adopted by major companies.
- OpenAI Apps SDK validates demand for rich UI in conversational AI.
- Proposal includes pre-declared UI resources, MCP transport for communication, and HTML support.
- Security measures: iframe sandboxing, predeclared templates, auditable messages, user consent.
- Backward compatibility ensured; UI is an optional extension.
- Invitation for community feedback, testing, and contributions via GitHub, Discord, and prototype implementations.
